Are all SP20s the same?

Is there just one kind of Spondoolies SP20?

I was offered an SP20 Jackson and an SP20 Dawson.  I am guessing that this is a simple mistake and that Dawson is actually an SP10.

And what's the difference between SP20 and SP20e?

Dawson would be an SP10, so probably a typo.

I think the E signifies that the mounting of the hash boards was improved for better durability during shipping.

That's correct, "SP20 Dawson" is not a thing and is an error. And the "e" is to signify they fixed the hashboard mounting but very few people use that moniker.

I dont have an SP20 to verify this but have read some older firmware updates were showing the the SP20 as an SP10 but this was fixed I think.So there is no Sp20 Dawson .

As I recall, the SP20E has slightly better chips, in the sense that the ASIC manufacturing process was yielding more chips that are in the highest range of "good". I think that the net effect is that an SP20E has a better chance of hitting the described 1.7TH hashing rate, compared to a November SP20 (no E). I can't speak to the other improvements as other folks have.
