Now that colour laser printers have dropped to a price point that you can have one in the home without thinking about cost, are there any "gotchas" out there that people have had experience with?

What are the pros and cons that I should look for when deciding which one to buy?

In terms of environmental issues, like old cartridge recycling, are there some cartridge types that can be refilled "better" than others? Or is refilling a complete no-go?

Thanks,

TJ
