Shot? One year of SL racing would do it, but 7 years of mostly staying in the garage and occasionally being skied by someone who doesn't know how to bend skis, not so much.
I agree, due to budgetary restrictions, I am using a pair of nearly 20 years old Head iSL 12mt 165cm (non FIS), which stayed un-used , properly stored in a cellar for their first 10 years of "life". For their second 10 years, only in the last two seasons I have used them SL for training and even then the days I've skied them "hard" can be counted on one hand, all the rest of the very few days i ski them, have been free skiing. Those were bought with the intention to be used when teaching the kids, in an era where "long boards" were still mainstream...

One other thing,
@markojp did mention boots...That's more important than skis, in fact. Which boots are you using ? If you are goin gto ski FIS skis for SL (and "proper" GS skis when training in the gates), then you need proper "racing" boots, not a "130" shop graded boot (even if it should be fine). And here is where most of your budget will end up. Whilst still skiable racing skis can be bought cheap-ish on the used market, specially at the end of a season, used racing boots are sa no-no for me. This because are often tweaked (aka boot-fitted) to the owner's specific feet and needs. But to drive a racecar, one needs everything that goes with it : suspensions, tyres, etc. Same for skis and boots...boots btw don't need to be extra stiff...just to mention, an "SS" graded - that's Super Soft - Dalbello DRS WC is stiffer than its 130-140 shop graded brethren (and more than enough to cause me some difficulty in adapting my skiing to them) - so choose wisely with the support of a good bootfitter and a coach's input.
