["Andy Whitfield" <andywhitfield2002@xxxxxxxxxxx>]

I've got plenty of double conversion UPSs in stock.  Also line
interactive UPSs (eg APC Smart UPSs).
The vast bulk of my stock is *not* listed on upsman.co.uk.
If anyone requires a UPS then please email me with your requirements
at
ups@xxxxxxx   or  andywhitfield2002@xxxxxxx
Thanks
Andy
