Its perplexing that you don't care about handling. Why would you potentially want to make a decent handling car handle worse and accept that for the sake of looks. That makes no sense at the best and is potentially unsafe to you and others at the worst.
That said, suspension is a package. Shorter stiffer springs require shorter firmer shocks to dampen them. Going the "cheaper the better" ebay route you rarely get the information or quality (and safe) product you need. Most of the time its just plain junk. The one spring that was referenced, the Voghtland, is from a quality German manufacturer. It, however, needs to be matched to a quality shock to effectively dampen it.
