Upgrading to SSD

I have a pair of Asus U1F laptops that I donated to some fantastic local students prior to their attending University. They have contacted me asking if there was a way to speed up these units as they are quite slow. No gaming is involved here but as my daughter and son-in-law both used these units for their university years I understand the problem.
I had bumped up the RAM to a 2 Gig unit giving the system a total of 2.5 Gigs.

I would like to install SolidState drives in these units eliminating many small problems now that most of these are reasonably price.
Your advice, please.

The prices are coming down, being tracked pretty closely in this thread: Best deals of the day

This also gives you/them the opportunity to get the best possible install which could be a real compromise of the SSD speed if it isn't up to snuff. We specialize in perfect installs of Win7 here having helped directly tens of thousands of users get them since Win7 beta, compiling everything that works best in this tutorial to Clean Reinstall Windows 7 which has been used by over a million consumers without a single complaint or return with problems if they stick with the steps, tools and methods given.

I should have also stated that these laptops use 1.8 inch drives are also 5mm thick and come with a ZIF (Zero Insertion Force) connector that uses a small ribbon cable to connect the drive to the interface on the PC. The black strip along the back of the cream connector is raised up to clamp the cable in place.
The HDD is 80 Gig, 4200 RPM PATA/IDE with that ZIF connector.
CPU is Intel Core Duo @ 1.2 GHz.

I hesitate to encourage you at all.

The most important component is the CPU. That CPU scores 516 on the Passmark.com CPU benchmark.

That's very weak.

By way of comparison, a 7 or 8 year old Intel Core 2 Duo E6600 scores 1554 and a 4 year old i5-2500 scores 6214.

I'd be highly skeptical of the value of any upgrade.

Thank you all for the advice.
Odd how we sometimes overlook the obvious.
I had not checked the CPU rating and did not realize it was so low.
Will discuss this with them and suggest that they save their money towards a new or much newer system.
Once again, thank you.
