Thanks for the long response and the suggestions. It seems that you're saying, in essence, that you get what you pay for. I don't think I am going to throw around that much money on a shaver; but, at least now I know the top of line and can look out for a sale. Halachikally, these shouldn't be a problem for me--I spoke to my LOR and he is more lenient in shaving matters than others.
Btw, it seems like you have a nice collection
Thanks again and have a good shabbos.
