There are lots of wine kits that are very good! If she likes lambrusco, maybe she'd like an "Island Mist" kit. They are kind of like wine coolers and not really my thing but I've tried some of them and think most women would like them. (I'm a beer and wine snob even though I try not to be). I had one that was kiwi something (maybe kiwi apple?) and it was good. They tend to be fast to make and sweetened.
As far as regular wine kits, there are many that vary in price from about $60 to $150. They all make 6 gallons. I use my regular primary 7.5 bucket but then I either use a 6 gallon carboy or a 5 gallon and a 1 gallon jug. I've made the cheaper kits and been very happy with them but I've sampled some premium kits and they are definitely better. The premium kits have grape skin packs in them, where the cheaper kits have concentrated juice. I've been happy with the juice packs, so I haven't ventured into the premium kits. You can probably find a good merlot kit for $75 or so. You will need corks, and a corker. Some LHBS rent them out. I've purchased 3 corkers because I didn't think I'd need an expensive one. I had the el cheapo one (insert with a mallet, yeah, right!), the $27 Gilda corker, and finally the floor corker. If your LHBS doesn't rent them, consider a higher end corker because corking is a major PITA. (I've never kegged and bottled hundreds of gallons of beer and never complained- 6 gallons of wine made me purchase a floor corker).
I made a Vinter's Reserve Valpollicella that I paid $57 for and have been very happy with. If your wife likes dry reds, she'd really like it. Lambrusco to me is way too sweet, that's why I mentioned the Island Mist kits. If you go online (AHS has lots of wine kits) and find a kit you'd think she'd like, I bet you'd be right. And by the way, wine kits are super easy. Much easier than beer, IMHO.
