I think that depends on how low you want to go. Drop spindles are the least invasive way to lower the front but cost a lot more than springs and only get you 2".

I am doing a drop on a 91 in the next week or so and just to save money I bought a 3"front 4" rear kit which consists of front springs for the front and blocks for the back, I'll let you know how that goes. The kit was only 199 on ebay, it may be [censored] but I'll let you know. If it's not low enough for me I'll add 2" drop spindles and block the back further.
