Good Lord! Some of you people have more than a dozen vises!? Why? I have one piece of sh*t vise that came in a Gander Mountain fly tying starter kit! To say this thing is "crude" would be a compliment! It looks like something hammered out of old beer cans by a group of small children chained to work tables! I am not sure, but, I think it is an AA vise....about $12 anywhere on the net and some places that includes shipping!
If anyone here is wanting to get rid of a working vise, I would be happy to take it off of your hands and make a little more room on your work bench....I would even be happy to pay the postage, so long as it didn't cost more than the vise! I saw the price on the Renzetti vise......it costs more than my kayak and I have a damn nice yak! It's no Hobie, but, I like it.....even if I had to sell a gun to get it!
Old, retired, fixed income and numerous medical issues, but, I love tying flies. Almost as much as using them!
I have several vises because I like vises. I have more than one pair of shoes because my shoes have different functions. I've got more than one firearm because I like firearms. They do different things, like my vises do different things. I could probably get by with a cheap Indian vise, but I don't choose to do so. My vises far outshine my abilities and I don't entertain the belief that a great vise makes up for poor abilities, but hey, I happen to like the mechanical properties of different vises.
If you're happy with a single POS (your description) vise, God love you. I am not, and I don't see why anyone should question your choice, or my choice for that matter. I'm on a budget, but it's not like I'm on Welfare and I happen to like vises.
I like the way my vises line up on my bench. Fly tying for me is more than applying components to a hook. It's not a bottom-line sort of thing. Admit different tastes and you'll understand.
