Really depends what you’re going to use it for –
For XC, my Shand Bahookie is superb – there’s a good value one on ebay at the moment with it’s original rigid forks – I fitted some 130mm Fox 34’s on mine and it’s excellent…..
For something more gnarly, I recently sold my Stif Squatch as I don’t do anything “nasty” these days, but it was an excellent bike and the frame is really well made…..there’s a few of those kicking about on ebay too…..
In all cases, I’d be looking for lightly used s/h – prices seem to have lummeted so there’s some bargains out there!
