Altec A7 yay or nay?


I have the opportunity to buy  Altec A7 cabinets ($100 a pair) and Horns ($260 a pair) without any cones to either.
The cabinets and grills are in great shape as is the Horn.
My question is, is it worth a punt? as a DIY project that has to be done on the cheap.
Any suggestions as to alternative cones/crossover would be greatly appreciated. 
The chap does have the crossover also, not sure what he is asking though.
This is more of a whim purchase and not a necessity.
I know one thing, it is going to be hard to slip them into the house without anyone noticing, lol...

I'll check Great Plains Audio, and look at what they have cost wise. I indeed do own Oris 150's, Klipschorns (standard), Nagaoka BLH, and a pair of Impulse H1's orf in another continent. I like the idea/price of the JBL 2225 woofers. I got to say my better half is not smitten with the Idea of another pair of speakers in the house.Thanks for all your responses.!
Thanks for all your responses and comments, alas it was all in vain as somebody snapped them up before I could get to the persons house. 
On to the next venture......
but....take the $$$$$ you would have spent and pour it into your K horns....
@tomic601,

I've already purchased Horns and Beyma tweeters waiting in the wings for the Klipschorns, although I am not sure which route to take with regards to upgrades and $$$$. Lots of variables and lots of opinions. The Klipschorns I also purchased without ever hearing them or any other Klipsch for that matter. Guess I love horns lol..... 
They are impressive but they have their place. I like them much better with the 500hz horns than with the 800 hz horns. Any that someone saw with JBL anything in them had been Frakensteined. That's OK, you just should know. They are very non linear. They are very bright. They have dynamic range like nothing currently being sold to consumers. If you use D130s they will be extremely hot in the mids. They tend to be anyway. Probably a JBL 130A or any number of Altec 15" or a lot of things being made today. They aren't accurate, but they are very impressive. If you want to play the dead like you are there. They will do it. they can use a good sub woofer, but it will need to be capable of significant output. A good 1/3 octave equalizer wouldn't hurt them any. They can be used with the horns on top or in the vent.
