While agreeing with your statement in principle, it isn't always the case.
Also when buying a rod you get what you pay for. If it is on sale great, other wise you are just buying a cheap(er) fly rod.
You can say "you get what you pay for", but in my opinion, you can also very easily pay for more than than you are getting. One thing I don't wish to buy is a rod that is expensive because of the snob value and the replacement guarantee. The guarantee is fine if you break lots of rods and need to replace often, but if like me, you only rarely have a breakage problem, it just ain't worth it.
I have used loads of different rods and can adjust to using any of them, hence my £55 20year old Fibatubes still work for me but are getting a little bit shorter as the spigots/joints wear.
So I will be buying some new rods soon, but they won't be S, L, O, or the like.
Anyone know of rods that DON'T have snake rings fitted?
