You can use some clones like CnProg or Soclone

Other interesting opensource alternatives for you to check could be OpenMind and VoxPopuli

Good luck

I guess it really depends on what you mean by "low cost". UserVoice.com offers specials for startups and non-profits (50% off) & open-source projects (free). There's also a free plan. http://uservoice.com/signup

We recommend You use UserEcho customer feedback service to start collect ideas and feedback

Suggest Vote Comment Bribe is 100% free, but only works in Joomla

Well the latest & most intelligent of solutions for auto-feedback management and great interface is http://bubbleideas.com

It was launched recently at Singapore, and I can vouch for its awesomeness if you are one of those who worry a lot about your customers.

UserVoice is a good product (we use it). But you have to constantly monitor it for ballot stuffing because they provide no means to limit who can vote. We have a lot of cases where a customer will have 15 co-workers all go vote for their request.

But if you review every new user that registers and go delete the bogus votes then it's a great system.

Uservoice has several issues IMHO. Like it does not allow you to disagree with a thought, which is required in a wholesome feedback scenario. All ideas are given one-way track - up, which is quite funny actually if you look at long term effects.

In comparison Salesforce does a better job with its product Ideas and gives excellent amount of control to the admins to control bogus voting, spam etc.

As @Robert indicates above BubbleIdeas is another good product coming up but it still is in beta. GetSatisfaction has a terrible UI, and that's what keeps us away from them.
