Jseime,
I don't know how the market is for Savage 99s in Canada, but if you want to have a good selection, you need to go to Pennsylvania. At the last show I was at, back in October, there were over 100 of them for sale in various calibers, grades, and ages.
I looked VERY longingly at a nice one with an octagon barrel and perch belly stock, low 100,000 serial number range IIRC, chambered in .30-30 Winchester, but just couldn't afford it.
I've long wanted to get a shooter in either .32-40 or .38-55, but with those two calibers there only seems to be two grades available -- beaten into the ground and used as a fence post for 50 years, or pristine with high-end sights and special options, and neither is very affordable.
The common calibers, though, .243, .308, .300 Savage, .250 Savage, those will often be found in good condition and reasonably priced, anywhere from $300 to $600, depending on caliber, model, and grade.
Over 3 million (IIRC) 99s were made from 1899 until just a few years ago. They're out there, and they're still wonderful rifles.
My 99 was made in 1936 and is chambered in .300 Savage.
Someone sent me a link for a Savage 99F in .358 that's on one of the auction sites. Current price is nearly $1,400. I wasn't joking when I said they're sought after.
Here's a little trivia for for you all.
The Savage 99 holds the distinction for being made in more factory standard calibers than any other lever action rifle.
