That really depend on how you value your time, and the consequences of getting stranded. A poorly built wheel that's been ridden some is likely to have had the spokes weakened all over, so it may well continue to pop a spoke every now and then - even if you have them brought up to proper tension. If you can live with this (particularly for 36/32H wheels losing one spoke is pretty much a non-issue, they remain straight and rideable anyhow) then there's no need to do anything apart from replacing as needed.
But it can sure be a PITA to have such a string of nuisance failures, so a full rebuild with new spokes can be both cheaper and a lot less hassle. If bought new in oct you should have plenty of life left in the rim.

OTOH wheels, as bikes, are usually cheaper bought whole than in parts, so it might make financial sense to go for a brand new wheel instead.
Set aside some mone to have it checked over before you start riding though.

I have this aversion of buying more than needed, even if it makes financial sense, so I would probably go for a rebuild.
