Agreed...great time to sit back and see what comes up on the selling sites. If you have the time, time and time....there will/are good choices of used stuff.
Bashing and Nitro....I would go truggy. A good used Mugen, X2, Losi, Kyosho....etc are good bets. You'll need spare parts. Ask yourself "what does the LHS have on offer?"
But remember, unless it's a pull start ([:@][:'(]) you'll need a bump starter or starter box. You'll need batteries, receiver and transmitter, etc. And then you'll want to go over the purchase with a fine tooth comb and just check what may need replacing....[&:]
You'll need tools, oils, grease, bearings.....it's a never ending cycle of consumables...
But Mate....it's a blast of an addiction....(as you know)

....and a bonus if your better half likes it as well...
