I love a bargain and field grade SxS are there already. The only limiting factor is the cost of importing them. A 300 pound buy ($381.27), plus 25% to Holt's is a 375 pound invoice, which equals $476.59 and then quickly becomes a $1000 plus gun by the time you get it in hand. So cheap gun buys are relative and you need to take in the final total price including shipping. 300 pounds becomes $1,000.00 which is tripled, but a 1,000 pound gun ($1,270.90) only cost about a $2,100.00 total. Auction premium, taxes and importing drives up the final cost. So hear 300 pounds but know in you head that 300 is $1,000.00 in the end.
Still you can find a deal sometimes. I bought a Remington 1100 Sporting, 20 gauge that I had just under $700.00 invested in by the time it arrived. It was mint condition and I had been looking at several in the $1,700-2,100 price range. But no average gun worth a few hundred is going to be as much a bargain as you think. When the flood of old guns begins, and I expect it to occur in three to five years, there will be a few gems in the pile. It is just up to the buyer to see and buy them. Looking is 99% of the fun sometimes. A thousand pounds will buy a decent side lock, without a decent name on the side, in good condition, or a worn out named side lock or just about 95% of all box locks sold at Holt's. Sort through the box locks first.
