Really depends on your power level. IMO you can cheap out on rods. They rarely fail. Put the money in the pistons as they are the most commonly failed part. Wiseco. And if you're staying under a grand you don't need a fancy crank either (again, IMO), but cheap ones flex under big power.

DEFINITELY don't use a Compstar at 900rwhp if its a blower car... TRUST ME..
Call Callies, talk to Justin Whitman or Brook Piper, they'll tell you the same thing.
I'd trust a stock crank over a Chinese Compstar at 900 rwhp. 900 rwhp with a blower will flex a Compstar.
I think the Compstar rods are ok for 900-1000 rwhp... Even Callies will tell you not to push them over 900 CRANK hp.

I'm going thru this right now myself. Spent $10k on a motor, used Compstar stuff, 8k miles later, rebuilding the motor again because the Compstar crank flexed and took out #4 main.. $7k to rebuild/upgrade to Dragonslayer crank/Ultra H Beams.
Spend more upfront and save you a ton down the road.

You need to make those decisions with your builder. When I built my 402 I was thinking about 700 rwhp max, and the builder was going to use a compstar crank and rods. After a little thought, reality set in and I realize I would want more power so I upgraded at that time. Sure enough, now at 1000 I doubt the compstars would have worked out.
I always prefer to over build a little, rather than under build.
