I've heard good things about RicherSounds, and I like that they still have shops where you can go and poke the goods and turn the knobs, and go 'ooh, that's nice', while a staff member who might actually know about these products lurks nervously hoping you don't snap any bits off.
Conversely, we had a poor experience with JL here a few years back. They led us to believe gas connection was included in the price of a hob, then tried to charge us. Then when it became apparent they'd supplied damaged goods, they wouldn't disconnect it so we funded that before they would collect. We also funded connection of their replacement. Our letters of complaint were met with a dismissive replies from JL or ignored. I won't buy from them again because their comms were appalling. Honestly, I'm amazed they have a reputation for good service since we saw anything but.
