Thanks John - maybe if I need networking in my shed then :-)
I seem to have settled on this 3Com managed switch
(3Com Baseline 2916-SFP):
http://www.3com.com/products/en_US/detail.jsp?pathtype=purchase&tab=features&sku=3CBLSG16
It's actually discontinued now, but still available for around 150 inc
VAT. The HP Procurve switches are another 60-100 pounds, and I'm sure
they are better, but they are starting to exceed my budget.
Has anyone used this or a similar 3Com switch and have any good or bad
experiences to share?
Rich.
