nice find, Buckmaster. that is practically identical to the Cabela's brand sealer I bought new in 2004 for $299. probably made in the same factory. best money I have ever spent. the wide seal is much nicer than the thin line you get with the cheaper sealers. the only thing I've done to mine besides clean it is replace the Teflon tape (extra pieces came with the unit) covering the heat strip. I've sealed thousands of bags with it. best thing about these is that you can replace the heat strip or other parts as they are all available from Weston. indispensable piece of equipment if you hunt, fish, garden, make sausage, etc.
we used to buy bags and rolls by the case and split with friends to save money, but the best per bag prices I've found are on Amazon, most are prime eligible and I usually only have to by a couple hundred at a time instead of 1200.
