Buy one that is a well known brand and tested, and also from a trusted seller as advised above.

Buy cheap buy twice is a phrase said often and listened to not often enough.

Two reasons to upgrade.
1. A standard pump will flow a enough fuel most of the time on a modified car. It is when you give it beans the standard pump can not flow enough fuel at the top end. Hence why you need a pump that will flow more in that situation. A225lph will do the trick for most people.
(As well as the usual suspects also consider american stuff like these http://www.deatschwerks.com/products/fuel-pumps)
2. Fuel pumps get old. If it fails - engine goes bang. So swap out for a new one once in a blue moon from the safety perspective not the performance perspective.
To echo Shaun I ran a Walbro 225 at 450hp with no problems. And do not buy from Ebay

Most are just re-branded sytec (walbro) pumps.
Even the HRC's are based on Walbros but modded to their specs.
The SWRD ones come with a Subaru style sock so I'd be tempted to go with them.
A mate bought a 340lph RCM one, and for the money he paid I assume they also modded theirs too. Either that or their packaging comes at a bloody premium

If you change the fuel pump to an uprated one from a standard classic WRX, do you have to change the injectors and the fuel filter as well? Also what about mapping, will the car need re-mapping just because you changed the fuel pump? If you don't have to change the injectors as well

No need to change the injectors unless you're planning a power hike. Fuel filter doesn't need changing because of fitting a new pump but should obviously be done as part of your service schedule.
It wouldn't hurt getting your car on the dyno though just to make sure its running sweet. Its an old car now so checking things like the fueling can only be a good thing.

However saying you can't afford a £40-50 diagnostic run on a rolling road sounds a weird thing to say - if you can't afford that dude one might argue you bought the wrong car to begin with...
Personally I didn't get mine checked after changing the pump but that was because I was told by my mapper I wouldn't need to (and in fairness I was getting it mapped a few weeks later anyway)

Unfortunately as you evidently know these aren't normally cheap cars to run at the best of times.
