the browns are slightly better for gaming and although there classed as none clicky they do make a definatle click as the key passes the tactile bump. its just not an introduced click that the blue has. like i said they add an extra little bit of kit to make the click noise so in reality the blue key clicks twice (but there so close together it sounds like 1 click.) in overall feel there is little difference between the blue and browns. but the noise level of the blues does make them different. and defiantly loud.

as doe decent boards with blues. nearly all manufacturers offer a blue option there are a few option available at different price points.
http://compare.ebay.co.uk/like/271128258364?var=lv&var=sbar&_lwgsi=y&cbt=y this 1 was selling at around 50 last week but the price has gone up by over 30. still its worth looking it up elsewhere as im sure you will find something similarly priced (50-55) elsewhere.
zalman do a cheaper mechanical keyboard but i have no idea how well its made or how good it is as far as key roll over goes. it will set you back between 45 and 55 depending on where you shop.
but you best look about yourself.
amazon often do return deals where keyboards have just been sent back but arent 100% as far as packaging goes. they are still guarenteed to work but the box may have been damaged in previous transit. often these keyboards will be sold for as little as 50% or the rrp.
so well worth looking at.
