I’ve got 2 sets of skis and one set of boots that my kid has grown out of. Details are in the CL ads.
$75 110cm Fischer RC4 Race. A good beginner to intermediate ski:

$75 120cm Atomic Race 10. Wouldn’t recommend these for a beginner since they’re basically one step below a full out FIS race ski. If your kid is parallel skiing most hills and laughing at the other kids who still snowplow and avoid black runs this is the ski for them.

$50 Nordica Firearrow T2 boots. US 3, Mondo 21.5. The Atomics above are currently setup for these boots. A nice upgrade from the shitty rental stuff but still an easy to flex boot (my kid is super light and can’t even begin to flex most race boots).
