Yeah, by all indications the SP20 is a good little machine. I was really glad to see them make it instead of more industrial rack-mount gear. I hope they keep something in that market sector. Catering to industrial miners kills the landscape.
I'm anxious to see what ASICMiner does with their BE300s. I'd make a sexy home miner out of them if I had the dev time and money. Those guys have always made stuff for regular folks, though only one product ever as polished as an SP20.
ASICMiner was king no doubt when asics were coming out. But their prisma's did not impress me enough to get one even. I'm sure some will say V2 is great but I like others right now.
SP20 is amazing on it's ability. I was running full blast, but now I make as much to underclock and it does a amazing job.
The S5 again great machine. It was a nice addition to Bitmain's miners.
I personally am looking more twords next gen SP and Bitmain gear, unless something changes.
