We're slowly replacing our 2830's with 2832n's, which usually we buy via Insight. However, just recently our account manager has been telling us that their suppliers are having trouble getting hold of the 2832n.
Is the 2832 still being sold, or is it reaching EoL? (already?)
Where's a good alternative supplier for Draytek equipment in the UK?

We always use Broadbandbuyer for Draytek units and they are showing 100+ in stock at present.

There are loads available; I've no idea why Insight are telling you that.... "thousands" apparently.
