Bandsaw Advise - Please

[Black wallnut]

Have you seen and been able to compare to the 555X. On the face of it, it looks like a very similar saw but from a specs point of view the "X" seems to have the following extras.

1.5HP vs. 1HP for everyting I've done 1 hp has been plenty
Larger table I've been happy with what I have
Quick release blade tension Like Larry pointed out older G0555 have this
Cast iron vs. aluminium wheels I do not see how cast iron is a superior material
Cast iron vs. aluminium fence ditto
Resaw fence included Resaw fences are not hard to make
HDuty cabinet Not sure an enclosed stand is an upgrade
Light
Lower wheel brush again something easy to make for not much money.

See my comments above. I've not seen the X version in the flesh and I'm not likely to. The closest showroom is 4 hours away and closed on the weekends. larger HP might be an issue for some but since I do not do a lot of resawing of dense hardwood the 1 HP is fine. The real question though is are these upgrades of value to you as a potential purchaser?
