Picked this Monitor 17b up from Oxfam, of all places, advertised on Gumtree, all for less than £19 delivered. The pump felt good so after a quick coat of looking at I fuelled it up & off she went. I thought I'd pit it against the Primus 96 I bought from Simes at Newark. The Monitor (right hand flame) wins hands down for me - four pumps to a roaring flame! Paul.
