Your best bet is to buy a kit for your first plane.
If you want to experiment from there it is up to you.
Avengers are good

A couple guys at our club fly slashers

And one or two fly Gremlins, but I think they are upgrading this year.
But first you need to pick a class or find out what others at your club are flying , ie. Open B, SSC etc.
so here is a link to RCCA

and there are lots of other kit suppiers also.
