What is your budget? I would go with a new racquet - you will see a difference in 18 years of technology.

Wilson Sporting Goods : Welcome for their latest racquets.
I have a three year old Wilson N-Code 5. Great racquet - but a very stiff racquet - if you have issues with tennis elbow due to the vibration transferring to your arm via the racquet, then perhaps the N-code line is too stiff for your needs. You can probably find the N-code series racquets at Sports Authority or Model's.
Last year, Wilson came out with a K-Factor line of racquets. And I believe this year, they are calling that line the [K] line, as in [K] Tour, [K] Six Tow, [K] Brave, [K] Fury, and [K] Court. These look to be good middle of the line all-around racquets. I haven't used a [K] racquet, but from what I've heard, they are decent.
I got back into tennis about 4 years ago myself - I play every Wednesday - we have a foursome and over the winter time, we play in a bubble and have an hour of drills with a pro, followed by an hour of doubles. In the summertime, we simply play doubles for a couple of hours.
Just my $0.42,
