As far as I remember you can also talk to Dave/STI Tuning - he should have those for sale.
However I'd say the way you choose should depend on what do you expect from the car.
For daily driver I would actually rather go for new, rubber bushes, standard replacement.
Polybushes are nice in some sport applications, allright, but not in all of those even. - it's not only about the ride comfort, it's also about the more attention they require, needing some new grease sometimes, when the old one is out. Otherwise it will squeak a lot and also be more prone for damage - even if it's told to last forever, being strong etc.
On the other hand - much easier to fit/replace than standard bushes - but how often will you replace those in your car?
Droplinks - you will easily find many of different makes. Again - try STI Tuning.
