FWIW, I used Tekserve several times when I was living in NYC and found them to be good, albeit not inexpensive. If you search the forums here for CompUSA, you will find that many have been quite dissatisfied with their Mac service. Given the age of your iBook, I dont think I would spend $235 on it. If you dont feel comfortable doing the rather difficult HD replacement yourself, I would suggest selling your iBook for parts on eBay, and using the procedes and the money not spent on the HD replacement to purchase something newer and more reliable. If you can swing it, purchasing a refurb MacBook would give you a lot of bang for your buck. Good luck.
