IMO, you'll forget the cost difference very quickly. Get the PhaseII wedge type from Enco, who seems to have a permanent web sale on it, then get a dozen more holders from CDCO. It's the nature of either type that the locking handle position will vary depending on the fit of the particular holder. The CDCOs are only so-so in this regard, but even if you have to scrap one, they're so cheap it doesn't matter. Or glue in a thin shim. Also, be sure to disassemble your new import QCTP and clean out all the crud and re-lube it.
