I'd recommend 27-inch Vittoria Zaffiros as an alternative to the Panaracer Pasela TGs, which I've also used. The Vittorias are slightly cheaper, truer to the marked size, ride nicer, and have far less vulnerable sidewalls. They are also less prone to pinch flats. They also have a tread pattern that is much closer to being slick, which increases traction and may make them roll better. However, they are heavier and have stiffer sidewalls (blackwalls) and a lower TPI, so if performance is your goal you might be better off with the panaracer.
My experience with cheaper tires is that they're adequate and all about the same, but flat protection is nice to have.
