I’d certainly consider the ti planet x – the build they tested in 220 tri came in at about £2k with full dura-ace I think.
Personally, the soloist looks nice, but I would probably go for carbon or ti at that price point. The Time frames as have been mentioned are worth a look. You could well be in luck too given that we’re near the 2009 range switch, so some identical frames with a changed colour scheme may be quite a bit cheaper.
Plus I’ve heard varying things about the soloist, the primary one being that it feels too stiff. Other ones to consider might be the Dedaccia frames – they’ll be quality as they’re often rebranded and sold for more by other companies.
