Digtal Recording on a budget

I read an interesting article in "Vintage Guitar Magazine" last month (Oct 08 I think) which discussed recording with a budget in mind.
The equipment list included: microphone, headphones, preamp, digital recording software, and mention of pocket recorders.

My notes show software = Audacity v 1.2 for Macintosh, Protools and Krystal for the PC.
Headphones = Grado SR-60, SR-80
Preamp = Belkin Tunestudio ( which I think is a device that accepts an IPod, ad- hoc pockt recorder), or Micport
Microphones as AKG Blueline, Alesis GT-40, Schoeps Collette

I am always interested in recording techniques and non-overly complicated recording. Any one with tips tricks and advise is encouraged to write me.

Digital Recorder Round-Up

Listed are the street princes for pocket digital recorders capable of high quality digital recording. The consumer’s point of view is that a use with a relative simple to operate device which will work with their home computer. There is an emphasis for the Macintosh platform. Note than units which supporting Mac also support PC. Look closely to processor chips when making your decision (It may support Mac but only Power PC macs). Multi trac recording is nice— some are described here.

Are some devices better than others? Make customer support of the product a criterion for guiding your selection. Manufacture history and price point round out the final decision judgments. You make the wisest pick.

Other things included are it’s nice to plug in your external mic for recording so capable units are listed. Line out and headphone ports are mentions as well as connections to computers. Attention to battery type is included. Lists of specifications are provided for review and comparison.

Specifications presented originate from mass merchant sites and modified for use here.

Consumer point of view: Macintosh compatibility,
multi/high rate of recording (up to 96kHZ, 24 bit),
use of power adapters and battery use AAs—trying to stay away form internal rechargeable. Read reports of customer service denying warranty fixes in lieu of parts and materials repair which rival original cost of unit.
