Yep, I agree with the other posters here...the price is quite fair.
This is an expensive business, and buying an awesome tape echo that you can insert into multiple places, and have no maintanence for this price is a GREAT price IMHO.
AS billybk1 mentions, you do have a choice where to spend your money, and if it is too rich for your blood, then there are certainly other choices.
Hell, I have a mic that costs over $4,500, and another that costs over $3,000. Now I know this is not an apples-to-apples comparison, just to point out that when you look at the overall costs of running a top-notch studio, $250 is quite cheap.
If you are doing this for a hobby, and cannot afford the $250, that is completely understandable, but at the risk of sounding rude, that is not UA's problem. They have priced the plugin where they need to price to make money and to continue to fund their R&D. Consumers will vote with their wallets and in the long run, UA will either survive or they won't. That is what a free-market society is all about.
