In reply to Benstar:
Krukonogi Svarogs and Tvorogs...
And numerous others.
The few things to consider (if planning on gettin' some) is 1st to figure out what you want to do with them. The Tvorogs & Aspeeds are steller for hard comp-style drytooling or mixed... less so for verical to slabby technical winter climbing or pure ice lines.
And do you assume some or a lot of progression... Again. Nomics ain't really that useful for grade II gully snow plods, but if you think you'll be soon climbing continental ice up to grade 6 and scottish winter bashing to VIII (well, V or VI for scottish and 4+ for ice is the real breaking point where the ergo-tools start to make more sense), then they might. If your ambitions are lower... perhaps Sum'Tec would be a better option (new one, that utilizes Quark/Nomic/Ergo picks).
Another thing to consider is picks and how has the manufacturer done things in the past... Grivel is AFAIK the worst, having changed the picks now like 3 or 4 times. BD hasn't changed since Chounard came out with X15. I beleive this is also the same with E-Climb (so same picks for all tools and no problems with obsolete models). Petzl has tweaked the systems... so older models are not supported any more (at least without work). DMM has changed the picks once (AFAIK).... Cassins hasn't changed, but have 3 systems currently. And the rest, well "new" so not enough timeframe to get an opinion (but Aspeeds and Krukonogies will prolly continue to use the same "system" even if they come out with new models... because developping something new is spendy...). So if you foresee using the tools for 10-15 years... with Grivel you might be sh*te out of luck only after a year or two. So factor in the fact, that tools tend to last quite long ('cept Nomics), but getting spares might prove difficult after a while... also some picks just cost an arm and a leg... luckily there are cheaper aftermarket options avaialable these days.
