Incompatible Truvativ chainsets-ISIS and Powerspline

I thought a had a bargain S/H GT Avalanache 1.0 off ebay with damaged Truvativ 5D chainset and picked up new replacement also off ebay but unfortunately found this to have an ISIS fitting when the old one is PowerSpline
Problem is now I can't find a Truvativ 5D PowerSpline listed either s/h or new on internet so I feel stuck. Is there a new Truvativ model? Should I go for an alternative Powerspline fit chainset or should I even consider changing BB to a Powerspline model (but I guess the l/h crank will also be either ISIS or Powerspline)
Suggestions would be warmly received!
Whilst looking I found some reviews that were pretty unfavourable for the SD chainset anyway.

Do you mean a PowerSpline fitting? There isnt a fitting called 'SRAM', though SRAM is a biking term lol (manufacturer).
The bottom bracket has to match the chainset.0 -
Yes, you're right, it's PowerSpline (said powered by SRAM on the chainset so I guess that means it is matched to a SRAM BB)0

so you need a powerspline bb."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

This should do you:

What part is actually damaged?0 -
Thanks for that link..
It's the chainset that's broken-looks like your link may fit the bill, but I'm still confused by Tredz listing it as ISIS, but then specifying PowrSpline in the spec, but I can check this out with Tredz.
Should I stick with Truvativ or should I buy another (better?) 175ml Powrspline chainset that would match the chain (shimano HG) and cassette (SRAM 9 speed!)0 -
Powerspline is Truvativ only.
the cranks most likely come in both fittings.
TBH if you need to replace the crankset then change the bb as well as they do not last long.
Look at say a shinamo deore set up with bb."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Ah yes, description says PS, the header ISIS! Sorry about that!
Powerspline doesn't really go much above entry level, and I think the one I link to (in Powerspline!) is great value. Depending on how old the chain is, you'll probably need a new one with the new chainset.0 -
As Nick says, if need to change the bottom bracket because it is worn, might as well go for a superior system. Like this:

Comes with the bottom bracket - lighter, and more reliable package.0
