If your tweaks are minor, have you considered going to Photoshop Elements 9 which supports ACR v6 (and LR 3.x)?
Currently (starting 11/11/2011) , Costco has a coupon for $30 off starting next week ($50), and is at least 6 years newer than CS2.
As a side note- Adobe only allows updates of Photoshop going back 3 versions, so if you decide to stay with the full Photoshop, this is your last chance to get an upgrade price - when CS6 ships (probably at the end of 2011), if you want CS6, you will be forced to pay full price as CS2 will not allow for an update price.

Here's another thought on Supercharging Photoshop Elements for an extra $12, if you go that route.
Andrei Doubrovski (who publishes the As Simple as Photoshop series (ASAP)) also has a new Photoshop Elements tool to unleash paths, soft proofing, etc. Apparently, Adobe has developed Elements using the full Photoshop core, and if you know how, you can unlock some major features that would otherwise be off limits to Elements users. Sounds like a good deal to Elements users who don't want (need) to spend the money on the full Photoshop, but, can come pretty close for an additional $12.

ITEM: Andrei Doubrovski (
http://elementsplus.net) has released his $12 *Elements+* 3.0 [M] to unlock undocumented advanced functions in the program through dedicated dialog boxes. Features include paths, Smart Filters, channel mixer, soft proofing, layer groups, Smart Object functions and more.
-----------------------
Check out the hot link above for a list of all the features that can be "unlocked" from Elements versions 1 - 9.
As expected, unlocking is very version specific, with the most features to unlock in the latest Elements version (v9).
Good for people who want a great processing program cheap, with a lot of advanced Photoshop features they can work their way into using Photoshop Elements.
