What 2WD?

[Chalkie]

I'm looking to get a 2wd car in the near future, and would like a bit of help to pick one.
I fancy a Ultima SP2 or a TRF 201 but am open to other options. When I used to race I got on really well with the Losi XX, and prefered the original to the XXCR, so I guess I'm after something very smooth and stable above everything else. Also are spares easy enough to get hold of for those two?
