TainzeYou could always buy the Brown's separately. Skipping the switches in this drop saves you $45. Currently Browns are rare, though. You can search online with their SKU: MX1A-G1NN
Alternatively you could buy a keyboard with Cherry Browns already in them, then take them out. Looking online, they're about $80 (http://mechanicalkeyboards.com/shop/index.php?l=product_detail&p=72) for a new board, and cheaper on second-hand sites.
Unfortunately, a shortage is a shortage. I imagine that the next drop may not even have Clears! Blacks and blues are the only really abundant ones, and that may be perhaps because not as many people want them. That being said, buying less resistant springs and making ErgoClears is a really good option, too, as the bigger tactile bump is awesome.
