I had a murrays.. bought it used. it worked at first but develped searious leaks. i called murrays and they said (i still can't believe it) its suppoesd to leak like that??? i said it didn't leak when i first got it and that makes no sence. i tried to seal it with sillicone sealant (for tents and such).. didn't help it.
so i ordered a large one from SaltyDog.com after seeing my friends bag... i haven't tried it since i got it (last fall) but i am ready...
the blocks are the most expensive part...
PS i bet u will wish you spent the 200 if you dont get it and need it... heck i need a new tiller... 150 for a stick!
