First post too!

Hello everyone. I got started a month or so back with a block erupter from ebay. Been lurking and learning about cryptocoins and thought it was time to join. I'm even mining a few altcoins and keeping all the fans blowing, haha.

Hello and welcome!

How much did you invest in the block erupters and how much did you get in return?

tl;dr: was it profitable?

I paid $21 shipped from ebay. So far I've mined 0.029 on slush's pool.

So basicly no, but hey at least you didnt pay that moon prices they take here (>80€ for a single stick)

Am I correct that block eruptors are only useful for SHA based mining?  With Bitcoin valuation going up so far unless you have MegaHash hardware you can't really get a ROI. 

Thanks!

Yes sha 256 only, but other coins use that as well, though they are not valueable enough to make up for the energy costs. But that can change ofc.
High Bitcoin value is a good thing for miners, because it means their mined fractual bitcoin is worth more. His stick does ~330MH/s and costs ~2,5 Watt in energy depending on the energy costs 330MH/s = less BTC than you need to pay for 2,5 Watt.
