under $1000, ( ignore the list prices)
I paid $730 for my Easky LV (no rudder) two summers ago and the prices have not really changed much since then. 30% off sales are common in late summer. REI just had a 25% off coupon two weeks ago and often has 20% off ones. Plus you get the 10% rebate every year on purchases.
Try on the Astral V-8 PFD -- it is usually under $100 and is the lightest and most comfortable PFD I have ever owned, even on hot days.
I do advise you to lift and try to carry any kayaks you are considering. I know too many women who don't go kayaking as often as they would like because they struggle with kayaks that are too heavy for them to comfortably load and transport themselves. Yes, you can get fancy mechanisms for adding to your roofrack but it makes more sense to put that $200 extra cash into a lighter boat than into the roof rack. A longer thinner kayak is easier to load than a shorter fatter boat. I also think the Tsunami 120 is too wide for you -- you will find the cockpit too large and will be banging your knuckles on the gunwales. I don't understand why they make that boat so wide for the length, but I suppose they have to get the displacement volume somewhere. You really should try to test paddle it along with some narrower models to see what that feels like.
The kayaks I have recommended are not advanced models, just comfortable relatively light boats that are enjoyable to paddle in any conditions.
