Any gauge plans out there?

am loking to build a Bell 206 simpit. Does anyone out there have any plans for any of the gauges that are needed on the instrument panel? I looked on the Simpits site to see what I could get and it was really disappointing. I can purchase the 'real', aviation authorized, vertical speed indicator for $119.00. The 'fake' unit for simulation purposes is $220.00!! I do not get it. Please, if anyone has any pictures of completed gauges that they have built or have construction plans, lend a hand.
