My bf story... Once DD was home from hospital, she wouldn't latch on after dark and we cracked at 4am one night and went to Tesco for premixed Aptamil. A few days later we got a visit from a smashing BF specialist who advised me my boobs were too big and my nipples too flat - poor DD couldn't feed as she didn't have much to hang onto! 
It was expressing that saved our bacon - I pumped milk out when engorged in the morning and DH fed it it her in the evening once I was knackered. We also topped up with the occasional bottle of Aptamil but supply was never a problem for me. She was taking a bottle from about 3 days old and never had nipple confusion, we worked out that the best position for feeds was lying down and within a month she was feeding in every conceivable position. We BFd for 14 months.
I have a Tommy Tippee single electric pump which started conking out a bit after 8 months or so of more or less daily use. Noisy but quite efficient and comes apart easily for sterilising. Someone on gumtree is selling a manual Avent for a fiver which I might get as a backup.
fatpony - excellent work, love that fabric!
