hope I am not late or too late. The dealer must be selling you old model because canon models offer more dpi res than HP ones in same price, check below links
Canon Scanners
Canon Lide 100 -- price quoted in the site is INR 3,295.00
HP Scanners
HP Scanjet G2410
The above are single products from HP and canon in lowest range. HP pricing generally is lower in market than net price but canon you wont find much price difference.
bud, be proactive when you go checking something always remember model names, because internet gives you option of getting complete details. That is what I do when I am looking for some new product.
Canon after sales are not good - source of this information. If dealer/shopkeeper is the reference, you know how they work, they always say negative about things which gives them lower profit or costs lesser LOL. Best thing is again to check over the internet about complaints made. But for one thing which I have heard is some Canon service centers are not good in service providing, but frankly speaking I have lesser idea about this as I do not own any canon product, but IMO canon should be having service similar to HP. These days you need to log a call to customer care get a reference number(ticket number) for your issue and then give your HW to local service center or they send someone to have a look at your product. I know this from my personal experience in HP, Samsung, APC, Lenovo. Canon has good repo in the market so I guess their service should be decent and not pathetic. So, you can check with the Canon customer care calling them what is their process(what information they take etc etc) and which is your nearest service center, verify warranty of the product by product number/serial number. If you have doubts it would be good you know their process beforehand.
the service issue is always bad when the local service center or dealer(from where you bought) are bad.
