you can never go wrong with paradigm (assuming they're in good operating shape, obviously). buy second hand, keep em as long as you need em, and sell them for little or no loss when you've found your "longer term" speakers.
jeff's suggestion of totem model ones would be great if you can find one in that price range, although i think they may be a little pricier. totem rainmakers are probably closer in price, but i can't comment on them.
the epos, eras, and silverlines you mention have failed to impress me IN LISTENING ROOMS (i.e., i have no real world experience with them). they all sounded small.
the paradigms aren't the warmest speakers out there, but your arcam will help that a bit, and, as you say, you have a sub to fill out the bottom end.
studio 40's would be perfect for you and the v2's come in around your budget. the studio 20's are really good, too, but i don't have any real experience with them.
good luck
