The surround that its mounted in looks to be like the one I bought a few years ago and it was $140 or so.
Most of the nicer 5 guage cluster packages will set you back around $400 with the surround you have.

These have Dolphin\Shark guages which are bottom of the line ( I have these and hate them) so figure new, yours would be in the $425-500 range.
