If you're looking for a 12ga, you can certainly score an original 700 for under $3,000. Probably one of the better values out there, especially if you're looking for a modern, reliable Brit sxs.
You might have to revisit that. A quick check of Roy's Auction report for 2007 shows W&S M700, 12ga's, listed as Ex Cond. selling for $3600-$4800. Just in March a composed pair went for $8913.
Woodcock Hill has a 26" version listed for $5250, and I have seen two 28" here in NY in the last 6 months listed at $3950 & $4100.
Granted you can find one in lesser condition for less money but in VG to EX they're up there.
