The 5-shot magazines work just fine. Of course, they aren't sold retail anymore. I haven't had any trouble with the 10-shot ones, but I usually use my 5's. It takes a while to get over the "it's just plastic" for such a fine rifle.
I have found the 541-S to be more valuable than the 541-T. $600 would be a fair price on the 541-S in good condition. Remington made the 541-T with a sporter barrel and later with a heavy barrel. Based on what I hear, there is no noticable accuracy difference between the -T's regardleass of barrel. I have had a 541-S for years. I'm in the process of acquiring my first 541-T. We'll see how it does.
