If you are charged with doing small quantities of ADR then stick with what works best for you eg. PT's 3 beaps for cueing your Actors, paper scripts, paper check sheets for managing takes... However, if you do alot or will do alot of ADR then it makes sense to invest in solutions that will be of most benefit, have a short ROI period and fit seemlessly into your current workflow with minimal disruption. Having said that there's always compromise in introducing changes into your current processes (eg. Director, Actors etc have their own preferences). It's always best that when you do select a product that you get their buy in otherwise it will end up on the shelf.
Cueing Actors, Voices (V/0), Loop Groups etc, especially those that are new to ADR or just plain hate it can send Engineer's greyer and quicker than anticipated. VoiceQ ADR is a cueing application worth considering as part of your PT Rig. I suggest you download the 30-day full version first and trial it with your production crew (or wait for the latest version due out on March, 20th). If you and the team like it then you've got the latest ADR capability that you can promote as part of your studio arsenal of tools. Your then just a click away from adding Foreign Versioning to your service offerings.
Oh ... and yes, ADR software can be expensive BUT you'll be surprised on the quick return on investment. Talk with the guys at VoiceQ as I'm sure they'll give you a great deal ... If your going to NAB next month there's huge special discounts on offer at the booth (AVID Developer Community Area - Sl1413L). Hope this helps with your selection...
