for automotive use it is not a lot to spend, I agree, but you still have options.

I am using a Hantek3064 (Chinese) scope, which served me well until I took the step to invest in the newest PicoScope (a whole lot more expensive, don't even look at it if you work on low budget).

However, it seems like the Autel scope is about the same as the Hantek, tech wise, the software seems to be a bit better so if you have to choose, the Autel would be better.

That said, there might be other options out there that are worth to take a look at. I know about little pocket ones and other cheap scopes which won't do the same as the high end scopes but will serve you well in basics.

                     Buy a used Vantage Pro you'll get much more out of it than a basic one channel,two channel. I know it's over your projected budget but typically you'll find pretty clean one's on e-bay for about $750-$1000. If you want the latest and greatest database they are just over $1000.00 but you can update later for about $440 to get current. Their free PC program although not live is very good for capturing movies or just image shots. You also get a very good DVOM with graphing capabilities. I wouldn't bother with all the expensive ignition,pressure adaptors just high and low current clamps which you'll sometimes see sold with unit. As far as four channels you'll hardly ever need more than two unless couple being used on ignition and need to check one or two other signals at the same time. Aeswave has all adaptors or leads that you'll ever need including ignition. If your price point is a stretch at $500  they have a single channel U-scope under $200 that you can choose accessories.I still have two original vantages that are great DVOM's but scope capabilities limited and their getting too old so buyer beware and can't be updated that's why I said pro model. Even though shop has Verus Pro since tethered by USB connection mostly still use my old 2 channel LS2000 and vantage pro for scope work. Depending on clients in shop most people won't pay properly for scope usage it's more for the technician to learn different testing techniques that possibly save time and give you a window to the front end of problems instead of totally  analyzing the processed back door through scanner. Most shops and techs hardly use theirs so many are very clean and originally cost near $3000

                 Their not that much different in price point and the Modis would give you 4 channels plus a backup scanner but you need to check all the personality keys,adaptors and European coverage as some people didn't spring for coverage. On the down side most Modis were used as shop scanner that's why they usually look more beat up and I think early models weren't that good with the battery either but can't speak from experience. Their is probably not a better scanner all-around speaking up to 2010 and would give you coverage on older vehicles and sometimes you might get some scope accessories like low amp current probe or conventional ignition leads as that was the shop's scope but look carefully. Since I bought new I always liked the fact that my Solus Pro and vantage Pro the batteries were interchangeable when one went dead while working but that's not your case here. I don't know how much of a database Autel gives you with their scope if any but maybe others can be more enlightening then me LOL
