LED_ZEP is right, you do get what you pay for. Although I've had some Youngs kits turn out OK, Beaverdale are more reliable. Going up another rung though, I'm currently stuck on the Kenridge brand. I've tried various types and, at around £45-£50, they're more pricey but it's still under £2 a bottle for wine that has proved reliable, I certainly like, and everyone I've given it to has enjoyed.
About 3 months ago, after thinking about it for a while, I went for a £70 (it was on offer!) Kenridge Australian Whisky Barrel Shiraz. Now, that is something special. Even on bottling it has a much smoother, fuller taste but I'm trying to resist drinking it for another couple of months.
As it's coming up to the summer fruits season, you might try (say) a very cheap (it'll cost you the sugar, yeast and usual nutrient , sterilizer etc. only) blackberry wine. There's lots of recipes and they'll all generally produce an enjoyable wine, if you're especially careful about handling and hygiene, and wouldn't disgrace any table, if you get it all right.
You can of course go a little off the wall, if you want. For a very cheap dessert wine (and to test the ability of the Lalvin EC-1118 yeast I was using), a couple of years I brewed a demijohn of a mixture of sultanas, sugar, brown sugar and a large mugful of stewed tea ('for bite'), with the starting SG set to go to the maximum alcohol the blurb on the yeast packet said it would go to (around 18%). It did that, and produced a very drinkable after dinner dessert-style wine that's great with cheese and biscuits, or you can glug as a substitute for sherry ..... !
