For £45 you can't go too far wrong, there's a couple on ebay for about that now. If your getting the electrics for this then I'd snap it up. I don't know if the servo/esc/motor/transmitter are any good but you can replace them all as you go along.
If your just spending £45 on a bare RTR ( without electrics ) it wants to be in reasonable condition or perhaps already upgraded abit.
Saying all of this even in complete standard trim the're not off the pace just that perhaps bits of it may not last as long.
