Let's stop using the term DL killer. I plan to use mine until I stop doing this stuff. (I'm 60 and 15 years looks about as far out as I would consider likely.) The X18 looks interesting, but I'm not buying one. I still don't trust anything with that brand on it. Maybe someday, but not now or anytime soon. (And my DL1608 has been working just fine.) I also can't afford to be cavalier about upgrades. Someday this stuff will be easily affordable. It was a pretty large expenditure for me. (With retirement looming and two cars that are more than 15 years old and have more than 400,000 miles between them. At least the house is paid off now.)
