Just some ideas here. Many Sample developers have got a lot more market-savvy with their price strategies, and are solidifying customer loyalty with bundlles, discounts, pre-orders, etc. My general impression is that sample material is getting a bit more affordable in many ways.
A welcome trend for composers of course. I'd like to make another suggestion: subscription models.
There are a bunch of developers whose products I rate highly and who keep coming out with great stuff. Naturally I won't buy it all, but I'd love to have it all, sooner or later! Mostly I wait until a specific project comes up which calls for a product, but if you have it sooner, you use it sooner. I trust these developers to continue coming up with stuff which I would like to add to my library-sooner or later.
Let's say I would maybe spend $500 on a particular developers' products in one year. If I paid this developer maybe $35-40/month, we would both have a good handle on our cashflow. Another option would be a yearly subscription, where you pay one lump sum and are then entitled to all products which come out that year.
A few developers who come to mind (and have been perticularly interesting for me the last year or two) are Spectrasonics (of course), Tonehammer, 9 Volt Audio, Sonic Couture, BelaD Media....
One final request: if I could exchange all the customer points I get from the gas station for filling up my car for a new copy of Trillian; that would be very nice too- Eric? ;-)
