So I'm looking at replacement wheels for a Trek 7.5 FX. Bought it used, with the knowledge that the rear rim was worn out. Looking at slightly wider rims to move up to wider tires. Don't need anything too fancy. Don't want to spend more on wheels than what I spent for the bike.

Riding will be like 90% pavement, and maybe 10% packed gravel trails. Will be lucky if I do more than 500 miles over the course of the next year.

Are budget wheelsets like either of the 2 below, good enough?

Mavic A319 Silver Shimano T4000 Hubs Silver Road Bike Wheelset [741368] - $99.00 Velomine.com : Worldwide Bicycle Shop, fixed gear track bike wheelsets campagnolo super record vintage bike
Bikeman Wheel Master Hybrid/Comfort Wheelset 700c (ISO 622), Silver

Should I plan on having them trued/tensioned locally before install?

Also, if anyone can recommend any other on-line shops I should look at, I'd appreciate it. I found those 2 just by google searches, so I don't know anything about the stores themselves.
