I'd go for brand name.
Brand name doesn't cost much more now.
Brand name uses known top tier manufacturer chips mostly.
Generic uses unknown manufacturer chips mostly, and the spd may not be written properly.
I guess you mean Kingmax pc150. If you don't overclock, you don't need to buy pc150.
Is above price before shipping?
If yes, let me tell you some better buys:
Crucial pc133 cl2 256M $39.09 or pc133 cl3 512M $93.49 + 5.5 flat rate shipping.
Viking pc133 cl3 256M (infineon chips) $39.99 + sh - coupon at Amazon.
When dell had 20% off few days ago, you could get Kingston valueram pc133 cl3 ecc 512M for $78+sh. - that's even better deal.
When the $30 off 100 was still active, you could get that plus another 256M for $78+28-100+sh. - that's crazy deal.
256M is fine for normal use,
if you use photoshop, more is always better.
