Registrar Management Software

[Nameable]

I'm setting up a registrar and we need a back-end system.

I'm already aware of offerings from:
Tucows (OpenHRS)
Enom (RegistrarPDQ)
DirectI (LogicBoxes)
Archetopia (RegistrarInABox)
DotAndCo (Perl's Net-DRI and Net-EPP)

And I'm looking for more options to evaluate.

I don't have access to the registrars mailing list and I don't really know the best place to ask this, so I'm open to any and all suggestions of actual systems and other places to ask. Feel free to forward or repost this request to anyone anywhere, I don't mind hearing from sales people at this point.

I'd also appreciate hearing from anyone about experiences (good and bad) using any of the above solutions (as customer, owner, or employee of a registar).

bump - anyone?
