No. I do not know if they collect tax for NY/NJ residents at the time of the actual transaction or after the fact (by reporting it the respective state's tax board) but I understand that NY/NJ residents do pay tax on internet sales.
I just bought my D50 from Digital liquidators.com for $554.00, body only. As for cards, you can outstanding sd cards on the internet. I bought the new 1 gig 133x card made by Kingston Ultimate from ewave.com for $100 plus $6.00 shipping. And this weekend I bought a 512 Kingston Ultimate on ebay for only $36.00 plus s & h.
I also found the 18-70 lens on Ebay from Camita Camera and bought a 7 year Mack warranty on the lens off of ebay for about $22.00. There are lots of options out there but definitely consider buying the fastest cards by Kingston or the Sandisk Ultimate III, not II. Good luck. Don
offering gray market bodies for much less but I passed.
Also beware of the trap of offering extra batteries for exhorbitant prices and slow cards at exhorbitant prices. Shop for all accessories all over the internet. I have found lcd protectors, extra batteries and chargers etc. all over the place at reasonable prices. Don
I just received my D50 (body only), from buydig.com, and it's perfect. I received it in NYC one day after I ordered it, even though I opted for 5 business day shipping. I also ordered a digital camcorder from them recently, and received it after 1 day.
