I do not have a spare one for you but do have some advice for you. i'm currently using Avent manual pump and it isn't painful because you can control your force when you pump. As manual pump is considerably cheaper than a electric pump, i suggest you get one and from a less well-known brand such as tolly jolly. I saw one from NTUC fairprice but can't recall how much, i remember the price was very reasonable. If you dont't like tolly jolly, you can get Avent from John little or OG, currently they are offering 20% discounts store wide, i went there to shop for baby stuff just last weekend.
I also suggest you go and buy one tin of milk powder on standby, it came handy for me when i have low milk supply due to menses.
