Speaking as a newer guy on the forums, time frame and cost would be my concerns as well. Really looking forward to the xult bodies that are being made, but it took a little convincing with the wife to justify it. so i cant for sure drop a ton of money on an xvalve right now.
That being said, i would love to have a brand new shiny x valve to put into it
So for my right now serious answer, a colored x valve is dependant on cost, but in a month or so when i can justify another big paintball purchase, i cant imagine anything keeping me from buying one. I would be happy to make a deposit for a new valve (especially one with new engraving), and make full payment on completion.

Also, i just realized this thread is 4 months old, but i hope this is still a posibility.
