I agree with Tom T's review - I left Leslie's for the same reasons he did - the staff there had no idea what they were doing.
B & B came highly recommended to me from a co-worker and I have been going there ever since. Great customer service and very reasonable pricing.
I have a Hayward Poolvac and I've had it rebuilt here at a much lower cost than Leslie's has charged me in the past. You can also purchase a new unit here for less than some internet stores, so if you are looking to replace yours, call B&B first and check their price.
