Does anyone know where I can get a configurator so that we can offer some upgrade options on the website?

We're kind of limited to what we can buy from our distributers due to what products they actually carry. That being said, what we are trying to do is give some options based on whats available to us.

Example: Hard Drive (all with check boxes)
option 1: 1 Tb 7200rpm Seagate
option 2: 4 160Gb 10,000rpm Sata/Raid setup
option 3: 2 500Gb 7,200rpm Sata/Raid setup

We're offering Seagate for our hard drives because of the warranty. Seagate offers a 5yr warranty as for all the others offered by our distributer including Wester Digital, only offer a 3yr warranty.

Another example would be RAM.

We can offer a few different kinds of RAM by different manufactuers, that vary in price for the same capacity. This gives the option to save some money for the same capacity, but in all actuallity you sacrifice quality.

Example: (all with checkboxes again, all vary in cost)
option 1: Corsair 2Gb DDR2
option 2: Kingston 2Gb DDR2
option 3: Inspire 2Gb DDR2

Another example: Systems (we want to list 3 different prices)
option 1: Just the box
option 2: The box & OS
option 3: The box, OS, Monitor

We would like all this to work on the website. We'll offer limited options, like 3-4 per catagory, like the monitors for example, ViewSonic, KMD, Hanng, Motherboard #1, #2, #3, power supply #1, 2&3 etc.. and then do a running total/balance as the customer builds them online, and is tied into the shopping cart.

Any suggestions/help would be appriciated.
Thanks for helping out guys.
