Get down low where you can see the alternator. If it has vents in the housing, it's a 40 amp unit. If smooth, kinda tapered aft section, you have a 28 amp unit.
The 28a unit looks like a deep, steel bowl, while the 40a unit looks like a car alternator with a slotted, cast housing.

There really is only one brand. OEM. Honda. There is a Chinese knock off, but it hasn't been used by enough people, or for long enough time to be recommended.
How much are you asking again?
