If you're referring to the Crosslake ones, afaik they're no longer selling those unbranded Pake frames, it's just another generic unbranded frame. Also: they are very heavy (I have one). I would watch your local craigslist for a some nice butted vintage steel, some kind of low end model since you'll be stripping all the parts anyway. You could definitely beat $150. Also, 52cm seems maybe a little small for 5'7", what size is your old bike? Is it comfortable?

+1 on making sure your parts will fit though!
