Alternative options for Stryfe?

I wish to buy a flywheel blaster, but I found that Stryfe is discontinued and it cost 45 dollars or more now, almost twice of the price it was.

Any suggestions for better alternative flywheel blaster? or Stryfe is still the best at the moment? (in the aspects of mod difficulty, performance before and after mod,costs to mod)

Edit: Opps, forget to mention, Im currently in United States so 45 dollars means 45 USD
