I agree. Building a Polymer 80 in 10mm will give you something to do and after you have finished builinding it you will have a 15 shot 10mm that has the grip angle of a 1911 and the easy parts acquisition of a Gen 3 Glock. Every part is your choice and Brownell's, EBAY are easy sources. I built both a G19 and G17 which are both great shooters. Another nice thing is that you can start with the lower and "build" the pistol on your budget, over time. I will say that building a Polymer80 is not a "bargain", as all the parts you need add up. I figured my G17 and G19 cost me around $450 each as you have to buy the barrel, slide and parts kit.
I built mine a year ago and I don't know what has happened with availability in this crazy economy, but finding the PF45 frame kit might be your biggest challenge as 10MM is becoming a must have. Good luck
