(ET) Battery advise please

["Joseph Rock" <jerock solidtech net>]

All,
  OK - it's time to replace the battery set in my E-15.  From the quick
investigation I've done, the potential solutions are:

Trojan T-105
  - From the local dealer: $65 ea
  - Rated: 185 AH/hr(5 hr), 225 AH/hr (20 hr), 115 min @ 75A

Trojan T-125
  - From the local dealer: $80 ea
  - Rated: 195 AH/hr(5 hr), 240 AH/hr(20 hr), 132 min @ 75A

Interstate U2200
  - From the local dealer: $99 ea
  - Rated: ___ AH/hr(5 hr), 225 AH/hr(20 hr), 115 min @ 75A
  - Also have "econo" (used U2200, checked, label removed) for $50 ea

Sam's Club
  - Stowaway label at $47 ea
  - Rated: ___ AH/hr(5 hr), __ AH/hr(20 hr), 110 min @ 75A

  Is the higher capacity noticable? (as in, worth the extra $)
Thoughts?

thanks,
