Lines: 29 I have bought several from Meredith Instruments (602) 934-9387. Prices start at about $60 for 1 mw glass HeNe tubes and go up to about $125 for 7 mw units. HeNe heads (glass laser tube aligned and potted along with a ballast resistor inside an aluminum tube) go for $125 for 5 mw heads and go up to $300 for the 9-11mw heads. Power supplies are of the switched-mode variety and sell for $75 new. These units are physically quite small (1.0 X 1.5 X 3.75 inches for the adjustable output item) and can be supplied for use with various input voltages (9 VDC, 12 VDC, 120 VAC) All that is needed is a tube, power supply, ballast resistor (~ 80K @ 5 watt), suitable enclosure, and a source of input voltage. Those guys work fast! My goodies arrived UPS (AZ to TX) on the Tuesday after I mailed my order (with postal money order) on Wednesday. Twice! They also have onesies and twosies of higher power argon and other more exotic lasers as well as night vision items from time to time. Another supplier is M. J. Neal Co. in Orient, OH (I think). Prices are comparable, but I have not bought anything from them. Happy laseing leigh signature line is still backordered...
