Anybody have any experiences with purchasing after market fuel pumps (in-tank)?

For my XL-7, the Suzuki dealer pump will cost $360-460. (I'm assuming includes the sender and pump.)

If you do an online search, you can find any number after market pumps from all the usual suspects, prices can be as low as a $100.  They look to be pump only, or pump and a bunch of clamps and a pickup sock.  Can anybody offer any advice on the aftermarket parts?  Plug and play or do you need to do anything creative to make them work?

Example:

Looks like the same pump will fit my old 99 Tracker (same part number gets quoted on a Tracker search)

Thanks

fwiw, when I swapped the XL-7 drivetrain and electronics into my swb, I didn't want to bother dropping the tank to replace the fuel pump.  I believe the Tracker's (2.0 liter 4 cyl) pump had an extra wire that the XL-7 harness didn't require, so it was just taped off.
 
Long story short, I've been running my XL-7 engine with the 4-cyl Track/Vit's fuel pump for almost 60,000 miles, absolutely no problems.  Except for one wire you won't need (possibly...I was also swapping between an '02 and an '03), they're completely interchangeable.  So, if you should happen to find one pump is cheaper or more available than the other, fear not.

I ran a ford focus in tank pump in my 92 lwb sidekick....it was less than half the price
