At $130 i don't know how bad it could be. Even season long equipment leases usually are around $200.
I haven't heard of them, you'll def. outgrow them, but considering rental prices, if they are usuable for even just 4-5days, then you've broken even. If they are working well for you now, that's all the feedback you need.
The biggest potential problem I see, is not looking at money already spent, but being too cautious about avoiding spending future money trying to minimize each ski day's expense.
Don't get overly attached to this equipment, probably within a season, the equipment is what will end up holding you back. When you reach that stage, it's not that you will have less fun on the slopes, but potentially you could be having more fun if you had better equipment.
Outgrow means for me that when you improve in skiing, you are able to apply more mechanical force into your ski and you expect the ski to be able to respond to your input accordingly. You will also be able to make a variety of turns, and do not need the ski design to assist you in making the turns as much.
The most obvious factor is ski length. As a beginner, skis are sized shorter as they are easier to manuever and control, but the tradeoff is length that provides stability and control at higher speeds. The edge of ski is what controls movement, and the edge is the control surface. More length is more control surface-and manufacturers make use of it. Otherwise you're a passenger on a ski saucer.
Flex and ski design (sidecut) have similar arguments.
An advanced skier who's skis are more optimized for high speed doesn't need the slow speed ski for couple of reasons, 1) they have the skills to manuever at slow skis. 2) it is not as interesting for them to ski at slower speeds, they've already done plenty of that when they were learning. Exception maybe for ski school instructors where you see that sometimes they take out a short length intermediate or beginner ski.
Boots have a similar story.
