I'm a bang for buck guy, it's how I justify spending money on things I don't need but want. As long as I can find a purpose for it that something else doesn't suit and is reasonably priced, it's on. Lol
Anyway, because of that I'd go with one of the flipo 1911s. RIA, Metro Arms, Hi Standard, think there's another one or two that I'm missing, but they're all reported to be quality products.
That or a used item in good condition. Sarco had a few of the Systema that came with new Springs and other key parts that make it for a great buy!
