can anyone suggest the best strategy to approach this from a new miner's point of view?
1) I reckon the fpga's will be publicly available in about 5 months. A couple of people claim they already have prototypes, but I think it'll still be a while before they're released on a bigger scale.
2) Well I reckon if you bought all the parts for a rig today it'll take you at least 10 days before its up and running nicely. Depending on what you go for, you could only make 1.5 LTC or day. But a pricier rig could get you about 4 a day at current difficulty. Depends how much money you wanna put into it. Something to bare in mind though, is that there is a new coin being released almost every week. One of them is bound to make it big like Bitcoin and Litecoin. You could try your luck with solo mining one of them, and getting a large amount of them to sell and trade later.
EDIT : Just seen a couple of other posts, maybe less that 5 months. Probably would give it about 2 I think.
