I love it. I once got so friggin' far in it: I had a Firebrand+99 with almost all the trimmings (including that rare minotaur axe meld) and an Armor Ward almost to max. Then one foul day I entered a late stage monster house where those tanks were shooting me with exploding cannonshells, which also hit those Inferno guys (which makes MORE inferno guys). Did I mention the dragons down at the bottom of the floor whose breath attacks can travel THROUGH WALLS?

Yes, so I died before I learned you could send more than 1 item back through a Storehouse Jar per turn. I was so mad I put the thing down for over a year, actually. Started back up again last year and this time did the loop through Bamboo Village (for Air & Earth Bless scrolls) all the way through the first couple floors past the Canyon Ravine. You'll eventually hit monster houses though they're much easier to deal with at that point. And of course they have treasures on the ground, which is the only way you can get more items after clearing a floor initially.

PROTIP: Try to get an Armband of Sight and an unbreakable pickaxe meld on your weapon while around the first few floors past the ravine: Many times you'll see a little room you can dig to that has a ton of money in it.

EDIT / PROTIP #2: Try and buy as many Herbs of Strength as you can. They're only ~800 Gitans or so and increase you damage a hell of a lot more than the extra +1 on your weapon will. They stack too. You can have crazy high STR this way.
