Step up from Nakamichi 582 tape deck?


Have an option to acquire a very good working order 680zx.
At present have a 582 and was interested if those in the know would consider it to be a worthwhile upgrade?

Or would I need to go even further up the food chain? Zx-7 or 700zxl or?

I have just purchased a massive lot of tapes at pennies per tape so do not foresee me forsaking this medium anytime soon .. Lol.

The only "bad" thing is that WH won't transfer the warranty, but hopefully it will last years without needing it!  I do think I got a good deal based on the rebuild and am planning on using it a lot.  Many albums to record! 
680zx or 682zx would be a good step up from a 582.a zx7 is a step up again from the 680 series.i went from a 582z to zx7.
I am seriously considering a zx7 mainly due to bad luck run twice!

I purchased a 682 from ebay and it got lost by Fedex after they could not deliver it the first try as I was not in to sign . Then it was simply never seen again and Fedex after 3 weeks admitted they had no clue where it went, I got my money back from seller and hopefully they did from Fedex.

Second I then bought a 680 from ebay and this arrived safe and sound but just did not work correctly as advertised at all. So this was returned for a full refund.

In twenty years of dealing on eBay I have never had such a run of bad luck but stuff happens.

So now looking at upping the ante to a zx7 .

Maybe.......
Nak poker.  First you get thieved then you get lied to.  If you are lucky one of two people in the world will fix it for big $$ while you wait many moons.
You know you are a serious addicted tape head when you buy 200 rock tapes off eBay for $60 shipped.

And then buy a Nak 660zx just for a backup spare tape deck......
