The only problem I have with a part like this is that the intake tract is something that any performance enthusiast will want to muck with a fair bit. Take me, for instance - I bought a new accordian hose, then wanted to mount 2 BOVs, then switched to a MAFT basic, then switched to a MAFT PRO running a MAP sensor. So, I went from 4 connections to 5 to 2, and I could drop those if I wished. Further, I went from a pipe designed for the stock AFM to one that just fits a filter.
The price he's charging for these is very reasonable when you consider how much work goes into them... however, personally I'd rather have just a straight pipe with a 45 bend in one end. I'll get someone to weld this up for me soon.
