SP-Tech have assured there is no risk in pre-ordering the SP30, and going by past performance (short time though it may be) I see it as a safe bet.
Solid logic.
I'd also highly recommend preordering from knc, avalon, and bfl. Because we all know that if a company has shipped asics before, it's totally safe to preorder.
Sure there is massive unnecessary risk and it is unlikely to pay off considering almost all preorders end up shipping late/underperforming hardware when in stock hardware is cheaper.
And sure you probably won't be refunded in the case of catastrophic failure but you should take the risk anyways because it totally sounds like a great deal.
