I'm not quite too sure what 800€ converts to in USD, but I'll try to help!
If you're looking for a kit that can cover the pop/loud-rock stuff, I'm pretty sure you could get by with one of those Gretsch Catalina Jazz kits, you could have it all covered.
I only say that because the kits are relatively "cheap" and I've seen them play (and sound good doing!) just about every genre out there. Extremely flexible, and perfect for a in-house kit. A bit smaller sized kick drum than your "standard" rock kit makes it easier to move around and fit into tighter spaces... if that's a worry!

Read reviews and talk to other players! Over-all, this kit gets a lot of love for the sub-$1,000 market!
