castletonia:
On the 2 pump spas, you can run all the jets at once but with reduced pressure.  You then have the option of isolating certain seats with more pressure at the expense of turning off other seats.

MarKee:
The V84 will allow a little bit more control over each seat, whereas the 750 has 2 large diverters that control each side of the spa.  There are settings to where you can run all of the jets at once on both the 750 and V84, but for more intense therapy you will be adjusting certain seats or zones to an off setting, in order to allow for maximum flow to certain seats.  Both use the same pumps and internals.

Construction is basically the same between the 2 series. They have the same thick hand-rolled fiberglass shell construction.  Plumbing in the V84 uses a ribbed torsion hose with glue, but without a clamp. The torsion hose is kind of like a Chinese finger trap, once it is pushed on to the back of the jet, it can’t pull off because it has a ribbing to it.  The torsion hose is needed with the Vector jets because it eliminates the chance of kinking.

Either Spa would be a good choice, I would pick based on which one you like better. Some people prefer the look of one series over the other, which is purely personal preference. 

These spas are some of the most reliable on the market, and you won’t have any issues with getting warranty or customer service from the factory.  The factory is  a top notch organization.

The price you are getting is really good. I wouldn’t be able to sell it at that price pre-tax, so if you are getting all of that and they are including tax at that price, I would jump on it.

Thanks everyone with such detailed responses.  I really do appreciate it.  So just to confirm, the e750 is glued and clamped, where the v84 has a ribbed fitting and glued, not clamped.  Is one less likely to leak vs. the other down the road? 

HT34:
Just another quick question...does either the e750 or v84 base have an abs plastic pan, or is that only on the signature series? 

If they don't, does anyone know if it's an upgrade option?

MarKee:
The 750 uses the clear tubing which the factory deems a clamp is necessary for.  The V84 uses the torsion hose, which has a lot more grip to it, and I don't think it's possible to ever loosen or pull off, so that's why there is no clamp.  If you stick your finger in to a sample of the torsion hose you can feel the Chinese finger trap effect, which is what happen when the plumbing is stuck on to the back of the Vector jets.  I have yet to hear of a Vector leak from a plumbing connection.  Some brands and websites promote the clamping process, but it's not necessary with certain types of plumbing.

There is a plastic sealed bottom on both the Vector and E-Series, and there is a special type of cedar bottom frame that will not deteriorate.  It will outlast all of the components in the spa.  If you want the "pan bottom", you will need to go to the Signature Series.  I wouldn't be worried about it, I own a E-Series 435 with the standard bottom.
