Yeah, I'm feeling the same. Mostly though regarding the GPUs bought in Dec, those became worthless much quicker than expected.
Gridseed has done a great job at mass producing these and making it easy for people acquire them quickly. The downside to this is difficulty skyrockets lowering profitability.
I am very tempted to go in for more at the latest offer of $165/each for 20 units, but am beginning to think it might be best to wait until the price levels out at what the manufacture is willing to go to. KNC announcing a unit for $10K for 100Mh/s (for $100 per 1 Mh/s) also makes me think the price will continue on down.
When you put it that way ($100 per 1 Mh/s) I too find it hard to order more at $165 for 360 Kh/s
...but when is the KnCMiner shipping? Q2/Q3 2014. By that time I bet their 100 Mh/s will be more like 120-140 Mh/s for $10k. With the price of alts sinking lately I'm thinking it would be best to wait...but of course I wont! (this being a hobby for me...if it was a business, well...)
I also paid extra to get these early knowing that the distributor cost was in the $150-160 range (maybe less now). I was okay with it then and am still now. It was a short window of opportunity for distributors to make some great margins and who can blame them. If cost is currently $150 then a $165 sale price would be a margin of 10%...still not bad...well, less after shipping and returns/operations so maybe 5-8%.
At $165 these miners are about the same price to performance ratio of a 290x not factoring in electricity cost. The electricity savings is what sold me.
Edit:
KNC is now 250 Mh/s for 10K or $40 per 1 Mh/s! These should be priced at $14.40
