Any good tankless water heaters?

Folks:
I've got a 15-year-old 50-gal. water heater that I'm thinking of replacing. The water heater currently sits in its own outdoor closet attached to the rear of the house. The closet measures 100x26x30 (HxWxD, in inches). I'm also planning to add a water softening system that I'd like to put in the closet, but I can't put anything else in this closet with a 50 gal. water heater. I believe a tankless water heater would free up enough space in the closet to include the softener.
Are there any good tankless water heaters on the market today? I've read mixed reviews of the Bosch models on eopinions.com. Failing that are there any small tanked water heaters, >0 gal., designed to fit into a tight space?
Thanks.

If that's electric, forget it.
And for the price of a gas one, I would sooner bump out the "closet".

Whether or not you can get a tankless to do a good job for you depends on (just to name a few) the operating conditions
peak hot water consumption inlet cold water temp general water usage patterns elevation (dist above) from sea level

Does the outdoor closet freeze. Rinnai might make one that has a element to keep it from freezing, but what if it does not work, you loose an expensive unit. Rinnai, Takagi, Bosch are all good, I have a Bosch and am happy. You do mean Ng or Propane.

The closet interior is unlikely to freeze unless we have several days of below freezing weather, which hasn't happened in over 20 years. I live in Sunnyvale, California.
The closet has NG service for the existing 50gal. water heater but no electrical. I could run a new outlet to the closet if necessary and probably will need to for the softener if I locate it there.
Thanks.

Tankless water heaters are not simply drop-in replacements for existing water heaters. You will need a larger gas connections and maybe a larger flue. Your tanked water heater was probably 34-40K BTU/hr and had a 1/2" gas line. Tankless heaters might run 120-175K BTU/hr and need a 3/4" gas line. You will also need a large enough gas service connection so that you don't starve you other appliances (furnace, stove?, etc.) when the water heater kicks on. Talk to you gas company (PG&E) to find out if your current gas connection is sufficient for the tankless heater in addition to your other appliances.
