A few players off the top of my head who shouldn't be that far off our budget:
Steve Banks (out-of-favour at Hearts, would provide more experienced back-up to Buzz)
Dave McKay (always looked a solid,reliable defender which is something we've needed this season)
Gordon Greer (similar to McKay, think he's out of favour at Doncaster)
Graham Dorrans ( good creative wide player who would perhaps be available on loan from WBA)
Patrick Cregg (out-of contract i think, looked a good player with a nasty streak in him that we don't really have)
Simon Lappin (already know he can do a job for us , worth another try as he's not figured this season and we need something on the left-hand side)
Stephen Dobbie (Consistently prolific in the 1st division, should be capable of a step-up)
