One of the characteristics of VS pumps is that they can be efficiently 'turned down' to almost any pool size. Most of those pumps are natively a 3HP pump -- too big for all but the largest pools -- but they can be 'turned down' to an efficient 3/4HP pump.

But, another characteristic of VS pumps is that lightning strikes nearby often kills the electronics . . . which cost 70% or more of the cost of a complete new pump. So, if you DO get a VS pump (regardless of brand) be sure to get one of these, and have it installed properly:

and if you're going to buy it yourself, I think Amazon has a pretty good price:
