HP eAll in One - your experience?

I'm looking for an all-in-one printer for a small office and am looking at HP offerings. One inkjet (HP 7500A/8500A A List on pcpro) and one laser (HP LaserJet Pro M1536dnf).

Firstly, if you're printing less than 2000 sheets a year on average is it worth getting a laser (mostly mono)?

Secondly, HP has an e-mail feature where you can send files to print from an email account. Does anyone have experience how good this feature is in a live environment?

I get a lot of images attached to emails. So would this feature print those attachments on a full A4 sheet or just smaller preview along with email message? Does this feature extend to images compressed using winrar as well ?

You printer less than 2000 sheet a year so no need for laser.
l am a epson fan. Because you can always use a refillable ink cartridge which save you lots of money.
