If you are looking to save some money and get a good pump look up TRE Performance.
I've been using a high flow pump of theirs for about three years now. Other 96-99 guys have well, And recently the W body community is paying them a lot of attention with great results. To date, I haven't heard anything bad.
I paid $80 for a high flow pump for the car and $40 for a normal pump for my truck. 3 Years of testing and going strong.
Recently a Regal buddy paid about $80 for your type of pump.
