I've ordered 2 M1 Carbines from them: A sale-priced (1K & free ship IIRC) "random picked, you get what you get", and an original (barrel & receiver, flip sight, Type 2 barrel band) configuration high-number Winchester for 2K.
The "Sale" Carbine, which I expected to be only suitable for an old jack handle, turned out to be a "B" marked tang Underwood, which was made by Singer Sewing Machine, a high-wood Rockola cartouched stock and a rare early double bevel Winchester trigger housing! Yes, it did have a Type 3 rear sight and bayo lug, but it headspaced fine and the ME was ~1.5, TE of ~1.5 with an excellent bore. The other parts alone almost justify the purchase price.
The Winchester was all Winchester, except for the M2 stock and late Inland handguard, both of which I replaced with an original Winchester WRA-GHD cartouched stock and W handguard which I had in stock. This one also had an excellent bore with a TE/ME of just over 1.0. Good headspace.
Both Carbines had plenty of original finish; dirty, yes, rusty, no.
So, based on my personal experience, I felt I got a fair deal and I've got no complaints.
