Sure. I bought my first one about 15 years ago when the z-lock was kind of innovative.
We used to consider them starter suits, but they don't hold up very well to alteration, so I don't think we have one left that doesn't have a run in it.
What we do now is start a lifter off in a relatively loose Centurian and alter it as they get stronger and more confident in gear. I have Centurians that have been altered in the hips more than 10 times and are still in reasonable shape.
If price is an issue, I think trying to find a cheap z-suit (<$40 for new) is a good strategy as it will perform better than anything comparable, for the price.
However, if price is not such an issue, I would tell you to buy a size 40 Centurian and alter it as you become more comfortable with the suit.
The Gym in Plymouth, MN has some Inzer stock that I know they were trying to unload for cheap. You can call them at (763) 553-0171.
Don't know if they would ship or not, but maybe worth dropping a dime.
